4 Claims.

The object of my invention is to provide a window frame and sashconstruction involving novel features without sacrificing any of theadvantages of constructions now in use, the construction of the improvedframe and sash being simple, durable, and comparatively inexpensive tomanufacture.

A further object is to construct a window frame and sashes therefor withvarious features to make the construction more weatherproof than theordinary type of double hung sash windows now in use.

A further object is toprovide an improved method of holding the sashesin selected positions and eliminate the heretofore used sash weights andprovide means to prevent window rattle and noises as well as sticking ofthe sashes relative to the frame.

'Another object is, by means of elimination of sash weights and thenecessary boxes therefor, to make it possible to use a narrower windowtrim which enhances the architectural beauty of the construction.

With these and other objects in view my invention consists in theconstruction, arrangement and combination of various parts of my deviceas hereinafter more fully set forth and illustrated in the accompanyingdrawing in which preferred embodiments of the invention are shown, andin which- Fig. 1 is longitudinal sectional fragmentary view of a windowframe with double hung sashes in a closed position, disclosing a verysimple form of holding sashes in selected positions within the frame;

Fig. 2 is an enlarged horizontal sectional view along the plane of line22 in Fig. 1 except that parts of the sashes are shown one immediatelybehind the other;

Fig.3 is a view similar to Fig. 1, but showing a modified constructionof sashes;

Fig. 4 is an enlarged horizontal sectional view along the plane of line4-4 in Fig. 3 also with parts of the sashes shown one immediately behindthe other;

Fig. 5 is a sectional view similar to Fig. 4 with a modified form ofsash holding means;

Fig. 6 shows a fragmentary longitudinal sectional view of a window framewith an elevational view, partly in section, of part of the sash withstill further modified sash holding mans,and

Fig. 7 is a plan view of the arrangement shown in F18. 6.

Like characters of reference denote similar parts throughout the severalviews and the following specification.

In Fig. 1 is shown, more or less diagrammatically, a fragmentary part ofa window frame It), having the right-hand portion which is not 5 shown,preferably symmetrical and the same as the shown left-hand portion. IIare side jambs of the frame. I 2 is a top jamb and I3 a bottom jamb orsill. The side jambs II are provided with two parallel grooves M in thecase of double l0 hung windows which style is illustrated in the figure.I5 is a parting head between the grooves l4.

Slidably disposed within the frame ID are two sashes l6, having toprails I1, bottom rails l8 and styles IS. The styles I9 of the sashes l6are slidably disposed within the grooves M of the frame [0 and separatedfrom each other by the parting bead IS. The sashes have each projectingledges 20 along their styles l9, opposite each other, which partlyproject over the parting beads l5, as clearly shown in Fig. 2, toprovide additional weather protection besides the overlap of the sasheswithin the grooves.

2| are fiat friction strips disposed within the grooves M of the frame,preferably one within each groove. These strips bear against the stylesI9 of the sashes by virtue of the pressure of coil springs 22 inrecesses 23 of the frame I0. These springs are provided for preferablynear the top and bottom ends of the strips 2|.

The operation of a window made in accordance with the construction justdescribed, is quite simple and does not vary from one employing theusual form of sash weights. The window sashes can be moved quite easilyand by reason of the friction exerted towards the styles of the sashes,they will remain in any selected position without dropping, the tensionof the springs having been so calculated that the friction will begreater than the weight of the sashes. There is further tripleprotection against weather with the construction of sashes shown, namelycontact with two sides of each groove and the additional ledge 20alongside the style of each sash. 45

In Figs. 3 and 4 is shown a slight modification of the constructionshown in Figs. 1 and 2. The friction strip 2| is provided with metaldiscs 24 suitably secured to the strip, so that the springs 22 can beinserted into their recesses 23 in the frame without removing thesashes. The extreme outside of the styles 19 of the sashes are slightlytapering as shown-at l9a. By so shaping the sashes, greater friction isexerted against their sides as is obvious from an inspection of thefigure. The small end of the sash may be either at the top or at thebottom, as preferred, in either case, the flat friction strip 2| adjustsitself to the slightly inclined outline of the sash.

In Fig. 5 is shown a further modification in the provision of a tongueIla in the strip Ii and a corresponding groove llb in the style II ofthe sash to provide additional weather protection. In all other respectsthe construction may be identical with those shown and described hereinin Figs. 1 to 4.

In Figs. 6 and 7 is illustrated another modification of the sash for thepurpose of facilitating the manufacture of the sashes and theirinsertion, as a unit with the friction strips, into the grooves of theframe. In these figures, the sash I0 is rectangularly shaped, as forinstance in Fig. 1. Both top rail l1 and bottom rail II are grooved at25 to receive at each end an angle plate 2 having one of its legs "aslidably disposed within the groove 21 is a flat friction strip adaptedto slide within the groove ll of frame Ill. The strip 21 is fastened toand between the angle plates 20 at each side of the sash, so thatanother leg 26b of the plate I! is set into the end of strip 21 topresent a smooth surface toward the wall of the groove I4 and for allpractical purposes forms an integral unit with the two angle plates 28at its ends. Each leg 28a of the plate 28 is provided with a slot 280for the reception of a pin 28 secured to the top rail l1 and bottom railis, respectively. The coil springs 22 are inserted into grooves 21a inthe friction strip 21 and bear against the style ll of the sash. Withthis embodiment of my invention, the friction strips form a unit withthe sash, the pins II preventing the strips becoming disengaged from thesash, while permitting the springs to act against the strips withoutrestraint. Sashes made in accordance with this construction are mosteconomically manufactured as units and can readily be inserted intotheir frames.

It is obvious that the principles of my invention are equally asapplicable to single hung windows, such as winddws in railroad coachesand the like, and that either of the embodiments shown and described maybe successfully used for such purposes.

It is understood that various changes of form, proportions and minordetails of construction may be resorted to without departing from'theprinciples or sacrificing any of the advantages of the invention asdefined in the appended claims.

What I claim as new, is:

1. In a window structure, a frame having grooves, a sash slidinglydisposed within the grooves having its width narrower at one end than atits other end, friction strips within the grooves, and springs againstthe friction strips tgagausethestrlpstobearagainststylaofsaid s 2.
